Looking for some advice on the following Problem:
- Cisco 7930 Phones periodically drop out of the Hunt-Group
- Phones then Reset
- Phones Re-Register but in ITS mode
- No longer able to join a Hunt Group
- Can Make calls, but can only receive calls pointed directly to it's extensions
The system has been upgraded to the latest IOS (Not version 8) and has received the latest phone loads for the 7931 series, problem is still occurring.
If anyone has any ideas/suggestions or would like to share a thought on this problem please post your comments as it is an annoying problem and we have TAC this already 3 times and even they are baffled, but I really need to find an answer to this problem as the client is ultimately becoming frustrated with the whole thing.
Look forward to the responses.
